Semi-basement, windowless gosiwon, jeonse, studio apartment, officetel, dormitory. The host built the best luxury residential facility in Noryangjin, supplementing the sorrows and shortcomings from all types of self-sufficient living experiences. The guest created an independent living space that everyone would want to show off, hoping that they would not experience the same inconveniences as the host. In addition, through years of experience operating a gosiwon in Noryangjin, I have communicated directly with residents and received valuable feedback, so I know very well what inconveniences they experience. I wish there was an exterior window. I wish the window was bigger. I wish there was a private bathroom. I wish there was individual air conditioning. I wish the heating was warm in winter. I wish there were no bugs. All of these have been resolved. Now you can just focus on your goals.
